Information Verification During Natural Disasters
Video: Boston; when the

Boston Marathon Bombings
• April 13, 2013 - Bombings
• Reddit and 4chan users post photos of
possible suspects
• April 18, 2013 – NY Post front-page story
with photos of misidentified suspects
• Traditional media blames social media
Video: Social Media and the
Boston bombings (edited)
April 2013 - CNN

Carlos Castillo – chato@acm.org
http://www.chato.cl/research/
Selected quotes from CNN discussion
• “We could wonder if the NY Post would
have had this terribly irresponsible
coverage if it weren't for Reddit”
• “There were rational people on Reddit
and social media”
• “Do you think everything you read on Twitter
is real? -No, but it is hard to know”
8
Carlos Castillo – chato@acm.org
http://www.chato.cl/research/
Motivation
• It might be the case that posting funny
memes and verifying information using
social media require different tools
• The repertoire of mass-interaction
mechanisms we know of is quite limited
Context
10
Carlos Castillo – chato@acm.org
http://www.chato.cl/research/
BBC's User-Generated Content Hub
• Contrasting sources from social media
• Interviewing individuals
• Metrics
– Number of followers, number of reputable
followers, history of activity
11
Carlos Castillo – chato@acm.org
http://www.chato.cl/research/
Storyful
• “Social media news agency”
• Verification of authenticity of photo and
video evidence
• Time of day (shadows), weather,
landmarks, etc.
• Accents spoken, ambient noises, etc.
12
Carlos Castillo – chato@acm.org
http://www.chato.cl/research/
Many others
• Truth in social media is a
widespread concern
• Journalists
– Verify, verify, verify.
• Computer scientists
– Apply ML/IR/NLP/etc.

Other aspects

• Point-based system
– Gamification
– Social recognition / influence
• Subscription to crises, etc.
• Platform actively being developed

Carlos Castillo – chato@acm.org
http://www.chato.cl/research/
The interaction mechanisms we
know of are quite rudimentary
We can design specialized
platforms for mass interaction
for specialized goals

Information Verification During Natural Disasters

  • 1. Information Verification During Natural Disasters Abdulfatai Popoola, Dmytro Krasnoshtan, Attila Toth, Victor Naroditskiy, Carlos Castillo, Patrick Meier and Iyad Rahwan
  • 4. Video: Boston; when the media gets it wrong April 2013 – Al Jazeera
  • 5. 5 Carlos Castillo – chato@acm.org http://www.chato.cl/research/ Boston Marathon Bombings • April 13, 2013 - Bombings • Reddit and 4chan users post photos of possible suspects • April 18, 2013 – NY Post front-page story with photos of misidentified suspects • Traditional media blames social media

  • 8. 8 Carlos Castillo – chato@acm.org http://www.chato.cl/research/ Motivation • It might be the case that posting funny memes and verifying information using social media require different tools • The repertoire of mass-interaction mechanisms we know of is quite limited
  • 10. 10 Carlos Castillo – chato@acm.org http://www.chato.cl/research/ BBC's User-Generated Content Hub • Contrasting sources from social media • Interviewing individuals • Metrics – Number of followers, number of reputable followers, history of activity
  • 11. 11 Carlos Castillo – chato@acm.org http://www.chato.cl/research/ Storyful • “Social media news agency” • Verification of authenticity of photo and video evidence • Time of day (shadows), weather, landmarks, etc. • Accents spoken, ambient noises, etc.
  • 12. 12 Carlos Castillo – chato@acm.org http://www.chato.cl/research/ Many others • Truth in social media is a widespread concern • Journalists – Verify, verify, verify. • Computer scientists – Apply ML/IR/NLP/etc. Castillo C, Mendoza M, Poblete B (2011): Information Credibility on Twitter. Proceedings of WWW Conference.
  • 13. 13 Carlos Castillo – chato@acm.org http://www.chato.cl/research/ Time-critical social mobilization • DARPA Red Balloon Challenge
  • 14. 14 Carlos Castillo – chato@acm.org http://www.chato.cl/research/ Recursive incentives • Winner's strategy: recursive incentives Pickard G, Pan W, Rahwan I, Cebrian M, Crane R, Madan A, and Pentland A (2011): Time-Critical Social Mobilization.

  • 16. 16 Carlos Castillo – chato@acm.org http://www.chato.cl/research/ Crisis → Claim → Evidence • Crisis • Claim • Evidence Boston Marathon bombings Link to official police report An arrest has been made in connection to the bombings
  • 17. 17 Carlos Castillo – chato@acm.org http://www.chato.cl/research/ Example claims
  • 18. 18 Carlos Castillo – chato@acm.org http://www.chato.cl/research/ Elements of a claim Media, if available Location Title, description, dates, tags Weight of evidence for/against & importance
  • 22. Open the “submit evidence” dialog. Promotes this claim
  • 23. Evidence overlay in claim page Displays supporting media Allow users to vote evidence up/down, optionally commenting
  • 24. 24 Carlos Castillo – chato@acm.org http://www.chato.cl/research/ Other aspects • Recursive incentives – Recruiting is encouraged • Point-based system – Gamification – Social recognition / influence • Subscription to crises, etc. • Platform actively being developed
  • 26. 26 Carlos Castillo – chato@acm.org http://www.chato.cl/research/ The interaction mechanisms we know of are quite rudimentary We can design specialized platforms for mass interaction for specialized goals
